My  initial response to "footprint" vs "land pattern" is that land pattern 
refers  just to the pads onto which the component is soldered while 
footprint, IMHO,  refers to the whole enchilada, pads, silk, assy, 3D ... I create 
footprints  not land patterns for my PCB tool. So, for me anyway, both terms 
have a place.  Land pattern is a sub set of a footprint.
